Heatbreak or barrel of high quality all metal type in the inlet teflon only reaches the top of the barrel, the rest of the journey is through the metal interior of the barrel, it prevents the inlet teflon from touching the nozzle, making it suitable for high temperatures at which teflon can degrade. This type of barrel may require a few degrees higher temperature and is usually more prone to jamming than a Bore type heatbreak
The combination of copper and steel improves heat evacuation over a steel or titanium heatbreak, which means greater temperature differences between the block and the heatsink.
Valid for Artillery Genius/X1 with smooth extruder cover, anet et4, CR10, Ender 3, etc.
Bottom Diameter: M6 threaded
Upper Diameter: M7 plain
*Recommended to use thermal paste at the junction with the heatsink
**Non-original e3D item
